HDMI 2.1 Supports Larger Bandwidth, Higher Resolutions

30 November, 2017

During the first three quarters of 2018, the HDMI Forum will roll out its compliance test specification, so if vendors are ready ahead of time, products should be ready for Q4 2018. HDMI 2.1 supports an insane 10K resolution which throws the pixels up to a huge 10240 x 4320, up from the 7680 x 4320 that 8K is capable of. (And here we were just getting used to 4K and the idea of 8K.) But perhaps more pertinent is the ability to deliver a 4k/120kHz image combined with dynamic HDR formats. The cable incorporates low EMI (electro-magnetic interference) to reduce interference with nearby wireless devices. Resolutions up to 10K are also supported for commercial AV, industrial and specialty usages. For those who don't know, HDR stands for high dynamic range, which essentially offers higher contrast, vivid colours and near retina-searing brightness for compatible TVs and displays; Dynamic HDR does that but adjusts the settings on the fly to correspond with what's being displayed, which is pretty cool if you like that sort of thing.

HDMI 2.1 also supports Variable Refresh Rate, which results in smoother performance on-screen as well as Quick Frame Transport (QFT) which reduces latency. There's also Quick Media Switching, which is helpful for movies and video because it eliminates the delay (often displayed as a black screen) before content appears on the screen. It also introduces Auto Low Latency Mode, which automatically sets the ideal latency to give the smoothest viewing experience possible.

The HDMI Forum is an open trade association that guides the future direction of HDMI technology and develops new versions of the HDMI Specification. More resolution, higher frame rates, and more color depth.

SUPPORTING GRAPHICS, PHOTOS, AND AN OVERVIEW PRESENTATION are available in the electronic press kit at https://www.hdmi.org/press/press_kit.aspx. HDMI Licensing Administrator, Inc. HDMI LA provides marketing, promotional, licensing and administrative services; as well as education on the benefits of the HDMI Specification to adopters, retailers and consumers.
